Abstract

An object is to obtain a flame-retardant polyester-based resin composition that uses no halogen-based flame retardant, has high flame retardance, and is excellent in strength retention after long-term heat resistance test under high temperature. The flame-retardant polyester-based resin composition according to the present invention contains 100 parts by weight of a thermoplastic polyester-based resin (A), 5 to 80 parts by weight of an organophosphorus-based flame retardant (B) represented by the following general formula 1, and 1 to 20 parts by weight of at least one amorphous thermoplastic resin (C) selected from the group consisting of a polyetherimide resin, a polysulfone-based resin, and a polyarylate resin. (wherein n is an integer of 2 to 40)

Claims

exact text as granted — not AI-modified
1 . A flame-retardant polyester-based resin composition comprising: 100 parts by weight of a thermoplastic polyester-based resin (A); 5 to 80 parts by weight of an organophosphorus-based flame retardant (B) represented by the following general formula 1; and 1 to 20 parts by weight of at least one amorphous thermoplastic resin (C) selected from the group consisting of a polyetherimide resin, a polysulfone-based resin, and a polyarylate resin. 
       
         
           
           
               
               
           
         
         (wherein n is an integer of 2 to 40) 
       
     
     
         2 . The flame-retardant polyester-based resin composition according to  claim 1 , wherein the thermoplastic polyester-based resin (A) is polyalkylene terephthalate. 
     
     
         3 . The flame-retardant polyester-based resin composition according to  claim 1 , further comprising 5 to 120 parts by weight of an inorganic filler (D). 
     
     
         4 . A molded article of the flame-retardant polyester-based resin composition according to  claim 1 . 
     
     
         5 . The flame-retardant polyester-based resin composition according to  claim 2 , further comprising 5 to 120 parts by weight of an inorganic filler (D). 
     
     
         6 . A molded article of the flame-retardant polyester-based resin composition according to  claims 2 . 
     
     
         7 . A molded article of the flame-retardant polyester-based resin composition according to  claim 3 .
